I once got a network security specialist from Cisco (a friend of a friend) to crack my business website. He quickly identified the router as Draytek but after half a day was unable to get in anywhere.
He did indicate some funny social engineering attacks; for example I had some pics on another website hosted on the same server, taken with a Sony camera. Apparently, an email (with a keylogging trojan attached) purporting to come from Sony and containing a special upgrade offer on their cameras, does the job in a lot of cases
